Abstract: To reduce the beam reporting latency, a base station may include a sounding reference signal (SRS) indication to a wireless communication device (UE) as part of the transmission configuration information (TCI) transmitted to the UE, allowing the UE to receive a corresponding downlink signal using the same beam (or with the same beam) the UE used to transmit (or with which the UE transmitted) the SRS indicated in the TCI. The SRS may be one of multiple SRSs previously transmitted by the UE. The UE may transmit the multiple SRSs periodically and/or according to semi-persistent scheduling, or it may transmit them aperiodically. Therefore, the UE does not need to report the beam quality, and the base station may perform the necessary beam measurement(s) instead. Various parameters and conditions may be defined for the UE to support SRS-based TCI.

Abstract: A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.

Abstract: Techniques for physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) processing for multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PDSCH hybrid automatic repeat request-acknowledgement (HARQ-ACK) processing timing may include determining that a user equipment (UE) is configured for single downlink control information (single-DCI) multi-TRP PDSCH operation, determining a first PDSCH and a second PDSCH within a slot, wherein the first PDSCH and the second PDSCH are used in the single-DCI multi-TRP PDSCH operation, and determining a minimum HARQ-ACK processing timing for the first PDSCH and the second PDSCH using one or more symbols of the first PDSCH or one or more symbols of both the first PDSCH and the second PDSCH.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

Abstract: A wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

Abstract: Systems and methods for measuring at and reporting by a target user equipment (UE) of one or more positioning signals sent from one or more assisting UEs to the target UE are disclosed herein. The target UE may receive a positioning signal from an assisting UE according to a communication received at the target UE. The target UE may proceed to perform a positioning measurement using the positioning signal received from the target UE. The positioning measurement may be used by the target UE to estimate its own position, or the positioning measurement may be sent to another entity within a wireless communications system to be used in estimating the physical position of the UE. The handling of multiple received positioning signals from various sources, and the handling of situations where, for example, a transmission reception point (TRP) and an assisting UE may schedule overlapping positioning signals, ate also discussed.

Abstract: Methods, apparatuses, and systems are disclosed for compensating for cell identification delays that are beyond the control of the UE, in connection with standards-specified cell identification timing limits. In frequency bands including both beam sweeping and listen-before-talk (LBT) requirements, a cell identification procedure may be significantly delayed due to LBT failure at the base station and/or beam misalignment between the base station and the UE. Therefore, UE cell identification timing constraints may be dynamically adjusted to compensate for such delays. For example, the time window allowed for cell identification of a neighbor cell may be dynamically increased in response to determining that one or more SSBs were not available at the UE during an SMTC occasion. In some scenarios, if the timing increase exceeds a predetermined threshold, the UE may restart the cell identification procedure, e.g., on the same frequency layer or on a different frequency layer.

Abstract: This disclosure relates to techniques for performing wireless communications by rapidly moving user equipment device in communication with a network. The UE may adapt communication techniques in response to the UE's motion. For example, reference signals may be transmitted by the UE to additional transmission and reception points and/or using different configurations. Similarly, the UE may receive reference signals from additional transmission and reception points.
